Two sections of a class took the same quiz. Section A had 15 students who had a mean score of 80, and Section B had 20 students
Ksju [112]

Answer:

86

Step-by-step explanation:

In this question, we are asked to calculate the average mean score for a group of students split into two different emerging groups.

We calculate the total score for each of the groups. This is done by multiplying the average score by the number of students.

Total score of section A is 15 * 80 = 1,200

For section B, total score is 20 * 90 = 1,800

Overall score is thus 1200 + 1800 = 3000

We add the scores together and divide by the total number of students in both sections

Average score is thus 3000/35 = 85.71 which is approximately 86

If the graph is reflected across the y-axis, what will be the equation of the new graph?
Bumek [7]

Answer:

\displaystyle b)y =  { 3}^{ - x}  + 1

Step-by-step explanation:

we are given a exponential function

\displaystyle y =  {3}^{x}  + 1

we want to figure out the equation of the new graph reflected across the y-axis

remember that,

\rm\displaystyle (x,y) \xrightarrow{ \text{ reflection  over  y - axis}}( - x,y)

let y be 3^x+1 so,

\rm\displaystyle (x,y) \xrightarrow{ \text{ reflection  over  y - axis}}( - x, {3}^{ - x} + 1 )

hence,

the equation of the new graph

\displaystyle y =  { 3}^{ - x}  + 1
